Nearly half of all strokes can be avoided, according to the Stroke Association.

Speaking ahead of the launch of its Welsh manifesto for the National Assembly elections tomorrow, the association said strokes need to be on the political agenda.

Jon Barrick, chief executive of The Stroke Association, said: 'Stroke is the third biggest killer in the country and with Wales' ageing population, experts agree that the incidence of stroke can only increase over the next few years.

'But it needn't be this way.'

He said the association was urging assembly candidates to promote stroke prevention and services in a bid to cut the number of strokes.

The Stroke Association Manifesto for Wales Launch will take place from noon.
